I’m certainly not calling out anyone in particular, or saying that everyone does this, and no single-rated products are legitimate. But I’m just going off what I’ve seen said, and also off basic statistics - the low frequency of customers giving ratings would naturally lead to many products with a single rating, but also many (more in fact) with no rating. There are exceedingly few of the latter.
It’s true this isn’t a big problem, people really shouldn’t put much stock in a single rating of course. But it just bothers me more than other, perhaps bigger issues, because (1) it’s intentionally misleading as people assume ratings are from customers; and (2) it’s so incredibly easy for Epic to fix.
